Segmentation created successfully but not visible in Infra & Operations view

[Selvam]

Hi Team,

I am trying out the new Environment Segmentation feature in Dynatrace and facing an issue.

I was able to create a segment successfully using a host filter (for example, host.name = <hostname>). In the segment preview, I can clearly see the host and its related entities like processes, containers, etc., so it looks like the segment definition is working fine.

However, when I go to Infrastructure & Operations → Explorer and select the same segment, I don’t see any data (hosts/processes show “No data found”), even after changing the timeframe to last 7 days and resetting the view.

I expected the segment to filter and show the host and its related entities in this view, but it’s not happening.

Is there something I am missing in terms of:

• segment scope or entity mapping?
• coverage settings?
• or limitations of segments in Explorer view?

Any suggestions or best practices on how to make segments reflect correctly in Infra & Operations would be really helpful.

Thanks in advance!
